The placental membrane separates maternal blood from fetal blood.Oxygen and nutrients in the maternal blood in the intervillous spaces diffuse through the walls of the villi and enter the fetal capillaries.he fetal blood flows through the baby, out the umbilical cord to the placenta and no further.

NO, they do not share the same blood at all. The mother's blood carries the nutrients, oxygen and everything else the baby needs to the placenta. The nutrients pass through the placenta, but the blood does NOT. The baby's blood goes through the umbilical cord up to the placenta, picks up the nutrients and filters back through the baby's system. Mothers and babies often do not even have the same blood type. c c Â· 6 years ago.
